Iraqi police say a double suicide bomb attack in the western city of Ramadi has killed at least 20 people and wounded more than 30 others.

Police say Wednesday’s bombings appeared to target senior officials of Iraq’s Anbar province, of which Ramadi is the capital. They say the attack began with a suicide car bombing on a road near the offices of Anbar’s governor, Qassim Mohammed al-Fahdawi.

Police say a suicide bomber on foot blew himself up a short time later as al-Fahdawi was leaving the complex to inspect damage from the first blast.

The attack wounded the governor and killed his deputy police commander.

Anbar was a key base for al-Qaida militants and other Sunni insurgents in the years after the U.S.-led invasion of Iraq in 2003. Sunni militants turned against al-Qaida in 2006 and joined forces with the U.S. military, helping to reduce violence in the region significantly.

In other violence, gunmen shot and wounded an Iraqi judge and his wife in the northern city of Kirkuk late Tuesday.
